IMPROVED SPRING-BED BOTTOM.

The Schedule referred to in these Letters Patent and makingpart of the same.

To alwhom it may concern Be it knownl that I, GEORGE W. Moneum, of Sterling, in the county of Whitesides, and State of Illinois, have invented a new and useful Improvement in Spring-Bed Bottoms; and I do hereby declare that the following is a full, clear, 'and exact description of the same, reference being had to the accompanying drawings, andthe letters and figures marked thereon, which form part of this specication.

Elastic or spring-.bed bottoms have been heretofore made and patented, consistingof a series of slats, each combined through the medium of bearing-blocks, fixed on the under side thereof, with two shorter slats or levers resting or supported, respectively, at one end, upon the bed-frame, (which thus becomes a stationary fulcrum therefor,) and at the other in elastic loops or rings, secured to the long slat, at ornear its centre; and also of a slatted frame, supported in like manner, by means of blocks resting upon levers, suspended at. one end in elastic loops secured to the frame, and at the other upon the bedstead-fr'ame.

In the irst instance, however, the independent arrangement of disconnected slats produces a loose, disjointed bottom, constantlyliable to derangement and consequent inconvenience and damage, while in the latter, the bottom, consisting simply of a rigid slatted platform, stiff and unbending in itself, which, although supported upon springs, so as to yield vertically, cannot adapt itself ,to the form or position of the occupant of the bed, a'ords but little ease or comfort.

The object of my invention is to obviate the disad- ^"vantages attendant upon these forms of spring-bed bottoms by an improvement thereorn This improvement consists in combining independent, elastically-supported slats in pairs, by means of central blocks D, (to which the supporting-springs of the short levers are attached,) and bearing-blocks E, placed between the spring-supports ofA the levers and their fulcra on the bedstead-frame, and in uniting these" pairs in a series, by means of transverse iexible. bands G, extending from side to side of the bedstead-frame, and secured thereto, as well as to each pair of slats, so as to allow a limited independent vertical play of the double slats, and yet entirely prevent any lateral movement thereof, the whole constituting a complete, steady, secure, yet perfectly iiexible and elastic bedbottom.

To enable those skilled in the art to understand how to construct and use my said invention, I will proceed to describe the same with particular-ity, making reference, in so doing, to the aforesaid drawings, in which- Figure 1 represents a plan or topview of my invention; i 'i ,Figure 2 is a side view of thesame;

Figure 3 is a central cross-section thereof', at the line x, in iig. 1; and

marked O, and, as shown, are connected at the centre by blocks D', so as to be arranged in'pairs or sections,

as shown.

flhis arrangement -of the upper slats C, in pairs or sections, however, isnot essential, as each slat, C, maybe separate, and operate wholly independent from the rest, if desired.

Beneath each slat, G, or pair or section of slats, are:

arranged two levers, F F, one end of each lever resting on the cross-bars B B,at the foot and head of the bed, and the other and contiguous ends of the levers being each separately supported in au elastic ring, or

its equivalent, marked au, as shown.

The said rings are secured to the blocks, which connect the pairs of slats O C, as shown, by passing around a bar, d, which is firmly secured upon the under side of said blocks D, or said rings may be secured to the middle of the slats O in'any other suitable manner.

There are also secured to the slats G C, about midway from the middle to the ends, the blocks, or fulcra, marked E, which rest upon the levers F F, as

shown.

The slats, or pairs orv sections of slats G O, are secured together by leather orother straps G G, which are buttoned upon suitable knobs, screw or nail-heads, on the fulcrum-blocks E, the ends of the straps being secured to the bed-raves, or sides of the bedstead, as

shown.

Thus, when the pressure is brought upon the slats O, at the centre, both 'of the rings a a'yield, and give the required elasticity, and pressure applied at each end causes the corresponding ring to yield, thus producing an easy and uniformly-yielding surface, for the mattress to rest upon. M

lVhen the slats C are arranged singly, each slat,O, would require a pair of levers, F F, and the rings a a. could be secured in any suitable manner to said slats. By making my bed-bottom in sections or pairs of slats, and connecting them only by straps, as described,

each section of slats will operate independently, so farv as the perpendicular motion is concerned, but the strap connecting them prevents an independent lateral motion of the slats.

I .do not claim, broadly, supporting the slats of my improved bed-bottom upon short levers, combined therewith through the medium of stationary fulcra and springsand intermediate bearing-blocks, this feature of my inventionv being anticipatedin Letters Patent to Charles Weed, dated May 2l, 1867; nor do I claim a, rigid slatted frame, in combination ivith such elnstieally-yieldng levers, as found in the patent of S. J. Wingate, dated January 7, 1858; but

I claim as an improvement on said inventions,y and desire to secure by Letters Patent- My improved elast-ie, flexible, and adjustable bedbottorn, composed of slats C C, united in pairs by central blocks D, carrying elastic loops or rings, to receive the movable ends of the short levers F, whose fulerum ends rest upon the bedstead-frame, and by intermediate'fbearing-blooks E, bearingupon said levers, when these double slats are united in a. series, by transverse lexible bands G, secured thereto and to the bedsteadframe, :all substantially as herein set forth.

GEORGE W. MORRILL.
